FLORA OF ICELAND elements: Lycopodium clavatum, Stag's-horn Clubmoss

Lycopodium clavatum; The Stag's-horn Clubmoss is extremely rare on Iceland - in fact only known from one locality. It can be distinguished from all other (Icelandic) Clubmosses by the leaves: they have a long hair from the tip of each single leaf. Another characteristic feature are the stemsegments between the unfertile leafy parts and the sporangial cones. In between are sparsly foliated stems, the leaves on the sese stem-segments are also much smaller than the leaves on the vegetative stems. These features lead to a rather nude appearance of these stem-segments. On Iceland it is known as Burstajafni.
